From Heatwole's Guide to SNP:
The 0.8-mile section of trail between Furnace Spring and Little Stony Man is the original Passamaquoddy trail route, In 1932 George Freeman Pollock, then still proprietor of Skyland, had a trail built between these points. In several places you can see a trace of the old trail just a few feet up the bank. Pollock called this the Passamaquoddy Trail because, he said, Passamaquoddy is a Maine Indian word meaning "abounding in pollock" (a kind of fish).
